He told me that no ammo over 125gr should be shot in a light weight revolver and that only jacketed bullets should be shot. He stated that you cannot get a crimp tight enough on a heavy lead bullet to hold it in place during recoil in a light revolver.
I can see WHY he would say that, but I'm gonna call BS on his answer.
I believe that CCI can't get a crimp tight enough with an aluminum case to hold a heavy soft lead bullet without a crimp groove in place during recoil in a light revolver, but that's not the same as saying you can't get a heavy lead bullet to stay in place in a light revolver.
Also, I think the absolute prohibition on anything over 125gr in a light revolver is a bit over the top. Which becomes obvious since, as you point out, they recommended a 135grain bullet in their second call.
Good information--again, thanks for posting it. I'd say it's a good thing to know if you're buying plinking ammo for a small revolver and a VERY good thing to know before you load up an SD gun. (Of course 158LRN isn't a great choice for that anyway, but I've heard of folks doing stranger things.)
FWIW, I'll still buy Blazer, but only with jacketed bullets and absolutely not for self-defense, and I can't say that I'm happy with Blazer's response. If they know this is a problem, they either need to fix it or put a warning on the box.
